    Default How important are megapixels for a camera

    Mega pixels are an important part of photography, though there are other things like lighting, shake and focus which matter too.

    Megapixels matter and have a lot to do with size of pictures. For a normal sized photograph 2 Megapixel is fine. If a camera has a low megapixel count and a large image is printed then the image will lack quality and most probably be blurred.

    But having huge megapixel count on a camera isn抰 too necessary , you can go according to your needs and spend less on a lower megapixeled camera.

    A camera with 5 to 10 megapixel is very good if you are not a professional photographer. More megapixels don抰 really mean better camera, infact huge megapixel images account for a lot of memory space too

    Strictly speaking, from the amatuer point of view, any P&S camera above 6 mp is not adding any value.

    even 6MP is a slight overkill. I have never taken pictures above 2MP resolution as they take far too much space, and lets face it, how many of us print these pictures

    The only really really helpful feature i find in my camera is the image stabilization technique (or whatever you want to call it ).

    PS: Went to the shop for getting a DSLR, saw tooooo many options there, came back empty handed and totally confused. Will need to read up about the different lenses...

    I think mega pixels matter a lot, would it not mean you would have more clarity in your pictures then. True they take up a lot of space but compare a picture taken with a 5mp camera and a picture taken with a 10mp camera.

    You are misled in your opinion. The quality of the picture depends upon the CCD (charge coupled device) first and then the number of pixels. I have an old Nikon Coolpix 3.2 mp point-and-shoot (P&S) camera (CCD of the size of fingernail of the little finger or 16 mm? that takes 10 times better picture than the 8 mp camera of my Samsung Galaxy S2 (CCD Size rought 4 mm?. Go some degrees higher to a 10-12 mp DSLR which has a 24mm diagonal CCD and picture is 15-20 times better than a P&S camera with the same mp. Go to the highest quality DSLR such as Canon EOS 5D which has a full frame 35 mm CCD and it will outperform the other DSLRs of 24mm CCD.

    If the CCD size is same then more megapixels will most likely result in better picture. Lesson for you friend: Don't be ever misled by megapixels. On a similar not, don't be misled by digital zoom - digital zoom is some worthless crap, optical zoom is the true thing.

    Advertising is all about publishing numbers. The higher the number (as in most cases), the better you can say your product is. Sometimes lower numbers (e.g. elec consumption) means better product. No one tells you the real story. Same story is about sound equipment that publish power output in PMPO. PMPO stands for "Peak Music Power Output" and is a very ridiculous term. There is no standard way of measuring PMPO (standard way is RMS or Root Mean Square). But any crap figure is published and stated that this sound system gives 3000W PMPO. Another example is dynamic contrast ratio or DCR in flat panel TV and again we get ridiculous figures such as 4,000,000:1 contrast ratio when in reality the native contrast ratio (FULL ON vs FULL OFF) is more like 3000:1.

    Tip: Always do research.

    So we know now that mega pixals don't matter as much, but what if a camera took HD quality pictures?

    OK. I may be giving the impression that pixels don't matter (at all). That is not the case. There is no way of knowing the CCD size in the camera - no one ever publishes such data. But in general we know that P&S camera have a CCD of about 16 mm?or little more. DSLR is not everyone's baby - it is like a Enfield Bullet and not meant for the casual photographer. So choose a P&S camera from the likes of Canon, Nikon, Sony, etc. (no particular order of preference). Chances are, if you have chosen a P&S with a high MP, the camera is most like not going to disappoint you.

    Now, what exactly do you mean by HD quality picture? Define "your" HD in terms of pixels. HD (and SD) mainly refers to video. The definitions are as follows:

    Standard Definition (SD) NTSC 480i/p: 704 x 480 pixels
    Standard Definition (SD) PAL 576i/p: 704 x 576 pixels
    High Definition (HD) 720i/p: 1366 x 768 pixels
    Full High Definition (FHD) 1080i/p: 1920 x 1080 pixels - This is roughly 2.025 mp.

    Cameras have changed and advanced quite a lot. Even a 3.2mp camera will capture more pixels in a still photo. But when you are using a camera to capture video, then it falters quickly. Capturing video frames a 1920 x 1080 pixels per frame at 24 frames a second is not an easy job and only the high end cameras can process so many FHD frames at 24 fps.
